Question

If a central atom of a molecule only has two electron domains, what is the only possible shape the molecule can have?

• A. Linear.
• B. Bent.
• C. Pyramidal.
• D. Opposite.

Answer 1

The correct option is B Bent.

VSEPR theory tells us that such structure has a bent shape.
For example :
Water is a bent molecule rather than linear. The reason for this bent shape comes from the electronegative nature of the oxygen atom. The electronegativity of oxygen creates a dipole moment in the molecule
Explanation:
The central oxygen atom has four pairs of electrons. Two pairs are shared in single covalent bonds with hydrogen atoms. The other two pairs are not shared with any other atom (non-bonding pair).
